tramp-sh.el.

needed anymore.
(tramp-error-with-buffer): Show message in minibuffer. Discard
input before waiting. Reset connection timestamp.

(tramp-process-actions): Use progress reporter. Delete process in
case of error. Improve messages.
* net/tramp-sh.el (tramp-barf-if-no-shell-prompt): Use
condition-case. Call `tramp-error-with-buffer' with vector and buffer.

(tramp-maybe-open-connection): The car of
`tramp-current-connection' are the first 3 slots of the vector.
* doc/lispref/text.texi (Undo):

* src/atimer.c (schedule_atimer):
* src/fileio.c (Ffile_newer_than_file_p):
Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
* src/buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
* src/fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
(syms_of_fileio): Remove Sclear_visited_file_name.
(Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
file doesn't exist; this avoids an ambiguity with negative timestamps.
(Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
* src/systime.h (make_emacs_time, invalid_emacs_time):
Don't assume struct timespec layout; POSIX doesn't guarantee it.
(EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
* src/undo.c (record_first_change): Push (visited-file-modtime) onto
undo list rather than reimplementing it by hand, incorrectly.
Fixes: debbugs:14824

Problem reported by T.V. Raman.

* src/process.c (close_on_exec, accept4, process_socket):
Define these if !HAVE_ACCEPT4, not if !SOCK_CLOEXEC.

Monnier's patch).
* viper.el (viper-emacs-state-mode-list): add egg-status-buffer-mode.
(viper-version): version update.
(viper-go-away,viper-setup-hooks): function changed (Stefan Monnier's
patch).
(viper--lookup-key,viper-catch-tty-ESC,viper-uncatch-tty-ESC,
viper-setup-ESC-to-escape): new functions (Stefan Monnier's
patch).

All the above are command-line interfaces to ediff: facilitate calling
Emacs with the appropriate ediff functions invoked.
(ediff-version): version update.
This simplifies Emacs a bit, since it no longer needs to worry
about closing file descriptors by hand in some cases.
It also fixes some unlikely races. Not all such races, as
libraries often open files internally without setting
close-on-exec, but it's an improvement.
* admin/merge-gnulib (GNULIB_MODULES): Add fcntl, pipe2.
(GNULIB_TOOL_FLAGS): Avoid binary-io, close. Do not avoid fcntl.
* configure.ac (mkostemp): New function to check for.
(PTY_OPEN): Pass O_CLOEXEC to posix_openpt.
* lib/fcntl.c, lib/getdtablesize.c, lib/pipe2.c, m4/fcntl.m4:
* m4/getdtablesize.m4, m4/pipe2.m4: New files, taken from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* nt/gnulib.mk: Remove empty gl_GNULIB_ENABLED_verify section;
otherwise, gnulib-tool complains given close-on-exec changes.
* nt/inc/ms-w32.h (pipe): Remove.
* nt/mingw-cfg.site (ac_cv_func_fcntl, gl_cv_func_fcntl_f_dupfd_cloexec)

* src/emacs.c (main) [!DOS_NT]:
* src/nsterm.m (ns_term_init):

Use 'pipe2' with O_CLOEXEC instead of 'pipe'.

Prefer mkostemp with O_CLOEXEC to mkstemp.
* src/callproc.c (relocate_fd) [!WINDOWSNT]:
* src/emacs.c (main): Use F_DUPFD_CLOEXEC, not plain F_DUPFD.
No need to use fcntl (..., F_SETFD, FD_CLOEXEC), since we're
now using pipe2.
* src/filelock.c (create_lock_file) [! HAVE_MKOSTEMP]:
Make the resulting file descriptor close-on-exec.
* src/lisp.h, src/lread.c, src/process.c (close_load_descs, close_process_descs):
* src/lread.c (load_descriptor_list, load_descriptor_unwind):
Remove; no longer needed. All uses removed.

(Fnetwork_interface_info, server_accept_connection):
Make newly-created socket close-on-exec.
* src/sysdep.c (emacs_open, emacs_fopen):
Make new-created descriptor close-on-exec.
* src/w32.c (fcntl): Support F_DUPFD_CLOEXEC well enough for Emacs.
* src/w32.c, src/w32.h (pipe2): Rename from 'pipe', with new flags arg.
Fixes: debbugs:14803
lisp/simple.el (default-font-height, window-screen-lines): New
functions.
(line-move, line-move-partial): Use them instead of
frame-char-height and window-text-height. This makes scrolling
text smoother when the buffer's default face uses a font that is
different from the frame's default font.
